Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516474, here are decompositions:

5 + 31516469 = 31516474
47 + 31516427 = 31516474
113 + 31516361 = 31516474
233 + 31516241 = 31516474
317 + 31516157 = 31516474
467 + 31516007 = 31516474
593 + 31515881 = 31516474
617 + 31515857 = 31516474

Showing the first eight; more decompositions exist.
